Society should not replicate the power dynamics of the retail economy—where those who have the most means take whatever profit they can for themselves—within the secondhand industry. As shoppers divest from retail and shift to secondhand, they must commit to building something better. Rather than disengaging from secondhand shopping, they should instead engage with the industry more: use their position in this space—their access and ability—to help create opportunities that benefit all people in the secondhand supply chain. Because, if we replace our scarcity mindset with one focused on opportunities for cooperation, this moment of industry growth and increased engagement could be a chance to build a more fair future for secondhand fashion, all its stakeholders, and the planet.
